--- title: EAS Insights sidebar_title: Introduction description: An introduction to EAS Insights which is a preview service for projects using the expo-insights library. --- > **important** **EAS Insights** is in preview and subject to breaking changes. While in preview, it is free to use. **EAS Insights** is a service that will offer a view into a project's performance, usage, and reach. We are currently offering a preview of Insights that is available to all developers, and we will continue to roll out new features and functionality based on user feedback and suggestions. EAS Insights makes it easy to see the state of your app, providing information about usage across platforms, app store versions, and timeframes. ## Integration with EAS Update If you're already using [EAS Update](/eas-update/introduction/), we provide certain high-level usage insights without any additional client-side changes. This is possible because by aggregating data from client requests to check for an update into a limited Insights view that shows usage over time, as well as usage broken down by platform. ## Use the `expo-insights` library Developers can add the `expo-insights` library to their projects and gain more precise usage metrics (than those provided by just aggregating update requests) and additional breakdowns by app store version. Currently, the library is limited to sending client events only pertaining to cold starts of the app, but in the future we will expand `expo-insights` to offer new types of events and payloads, to support more advanced functionality. ### Installation To use the `expo-insights`, make sure your app is linked to your EAS project in **app.json** / **app.config.js** by running `eas init`, then install the library. After installing the library, create a build either with [EAS](/build/setup/) or [locally](/guides/local-app-development/). The library will automatically send events to EAS Insights when the app is launched. ### View insights To view insights data of your app, in the EAS dashboard, go to projects list, select your project and then select **Insights** from the navigation menu.
